(1} Use math to verify that, for a BOUkV "FEM system, the wavelength of the electron beam can be estimated Without the consideration of effects of relativity". (10I points) (2} The real resolution of electron microscopes under 300kV is around 0.2 nm, please explain why from two different aspects. (10 points] (3) For a lOOOkV high voltage system, the wavelength of the electron beam without] with correction [by using the theory of relativity") is 1.23 pm 0.87pm, respectively. Please verifyF the wavelength of the ebearn with IOOOKV acceleration voltage with the correction by the effects of relativity. (10 points) Note that: mass of an electron: 9.1 X 10 '31kg; electIon charge value: 1.6 X 10 '19 C; Planck's constant: 6.626 >
